Dynamic update of HTML text field

[hazg]

Hello,

I am looking to update a html textfield from javascript. The script produces a slideshow of images which can be viewed via next/previous buttons or a automatically via a time delay. I want a description to be placed above each corresponding image that will change whenever the image does. The text field i want to update is:

document.write("<input type=text name=desc size=50 value=\"Description goes here\"> ");

Here is the function i have in the same chunk of script that works out which image it is but this is obviously overwriting everything else:

function description() {

if(current==0) {
document.write('Image One');
}
else if(current==1) {
document.write('Image Two');
}
else if(current==2) {
document.write('Image Three');
}
}

Any ideas would be great - Thanks

document.write("<input type=text ID="desc" name=desc size=50 value=\"Description goes here\"> ");



function description() {

if(current==0) {
label = 'Image One';
}
else if(current==1) {
label ='Image Two';
}
else if(current==2) {
label = 'Image Three';
}
document.getElementById("desc").value = label
}

Here's a working example of a slideshow that I wrote and have used several times. It's simple and uses JS objects.
